FINISHING DEVICE.

Application filed March 5,

To (ZZZ whom it may concern Be it known that I, EDWARD B. LIMLE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain Improvements in Finishing Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

My invention relates to finishing devices, it having particular reference to devices for burnishing or polishing portions of shoes, as the sides of the heels.

The heels of shoes, especially those for women, differ greatly in height and form, some being excessively curved and these curves varying from season to seasoneven in the same style of shoe. An object of this invention is to provide a burnishing or finishing device which is to a large extent selfconforming'and which may, in any event, readily be adjusted to different dimensions and forms of work.

To the above end, a feature of the invention consists of a revoluble member by which a series of work-engaging members is carried and which is of such character and so mounted that it may yield under pressure applied to the work-engaging members. I prefer to attain this yield by making the rcvoluble carrier member itself flexible, there being shown a series of such members upon each of which a series of finishing members is hung.

In order that the finishing members-may thus yield to conform to the surface operated upon,'in addition to the yield of the carrier member and at the same time to exert a positive rubbing action, as a feature of the invention each finishing member is mounted on two carrier Inembers,'sothat said finishing member is free to move, and

yet after a certain movement under the pres sure of the work is held against further retreat. I have shown for this purpose openings in the finishing members through which the carrier members pass, these openings being elongated and converging toward the axis of revolution.

As a further feature, finishing members mounted in a series upon the carrier'are tapered at adjacent sides from their work-engaging surfaces inwardly. This enables Specification of Letters Patent.

them to yield or tip laterally with eonsiderable freedom better to conform to the curvature of the work, yet maintaining as nearly as possible a continuous work-engaging surface.

In addition to the flexibility of the carrier members and the yield of the work-engaging means, as means for adapting the device to different forms and dimensions of the work, a feature of-the invention is found in relatively adjustable supports for the carrier members. Such an adjustment may cause the same length of carrier member to assume different curves during its revolution. Moreover, the supports preferably have attaching means for carrier-members of different lengths. This is here disclosed as consisting of slots in the supports opening outwardly, yet so inclined in the direction of the carrier members by centrifugal force.

ther features will be developed in the following detailed description, taken in connection with the accompanying drawing,-

Figure 1 of the latter being a view of my improved finishing device, partly in side elevation and partly in central vertical section;

Fig. 2 a full end elevation looking from the left in Fig. 1;

Figs. 3 and 1- details in side and edge elevation of one of the finishing members, and

Fig. 5 showing in detail the securing means for the ends of the carrier members.

As support for the artive portions of the device, I have iliustrated sleeve 1!) adapted to receive the shaft of a burnishing or other finishing machine, to which it may be secured to rotate by a set screw 19. One end of the support is provided with a head furnished by an annular flange let. integral with or otherwise ed upon the sleeve, while near the opposite extra iity the sleeve carries a i'novable head cons sting of an annular flange 16 projc ting from the inner end of a collar-l8. The collar is lliflti agaii t rotation upon the sleeve. while being j ustable through a considerable range towe rd and from the head left, by a spline and groove indicated at 2 A set screw threaded through the collar serves to lock it in the position to which it may be adjusted longitiu yofthc sleeve.

The direction spaced circumferential series, there being twenty here shown and consisting of sections ble or the l1ke,'oi such fiexlb hty action of-thecentritugal force generated by its revolution and that oi the members which it carries and to yield lnwardly under the pressure oi the work. Fixed on the endof each section of the cable and lying within the slots are externally threaded fittings 26, v which are clamped to the heads 14 and 16' by nuts 28 to retain the cable sections inplacefl This construction permits ditter ut lengths of cables to be introduced through the ends of the slots by'merely looseningthe securing nuts, whiletheir outward displacement when clamped-in place is resisted, not alone by the frictional engagement o'" e able component of the displacing force which is rad1al and therefore not effective to'move thefit'tings along the slots. Moreover, sincethe inclination of the slots is in the direction of rotation, the pressure of the work tends to force the fittings toward the bottoms oi the slots and still further insure their retention.

lhe cables 24- carry the work-engaging or finishing members proper. In the present embodiment of the invention these finishing members are in the form of disks Eh), each provided with elongated openings or slots 32, to receive adjacent cables. The slots 32 extend "from points near the opposite sides of each disk toward one another, beiu g inclined inwardly in the direction of the axis of revolution i ks-illustrated, their adjacent extremities are separated by a portion 34 of the disk. When the sleeve 10'is rotated, the revolution of the cables and disks causes them to assume the positions shown in Fig. 1, the cables occupying cate nary curves, while the disks extend radially outward withedges of their widened outer work-engaging portions 36 in contact withthesides of the adjacent disks of each series The series 01 disks, considered circumferentially of the support, are in close proximity to one another, this arrangement tending to give a work-engaging surface as nearly as possible continuous. At this time the inner ends or the slots at 34 are forced against the pairs of adjacent carrier cables. As the -work is pressed against the engaging surfaces 36, both the cables and the disks may yield to enable the operating surface of the device, considered as a whole, to accommodate itself to variatlons 1n contour, yet offering enough rcsistance to give an effective polishing action.'

. freely. As they turn, however, under suiticient pressure, the outer end of one oi? th slots of each disk contacts with its cable, stopping the rotary shift of the disk to give a positive: rubbing in addition to the sell conforming action. Thework-engaging sun face. of each disk is oi maximum width @011." sid eredlongitudinally-0t the cable, 1 sides 38 tapering inwardly therefronnpr lerably to points etU beyondthe cable. This air-angement facilitates the lateral yield of the dis I they having room to tip or shi tabout 'lulcro. furnishedby the contact of their outer edges at42' with adjacent disks. v

In using the device, such lengths of cables, each with their series 01 disks varying in accordance with the length, are attached. to the supportingheads, that when'the sleeve 10 isrotated by the shaft of the finishing machine to which the device is applied, the work-engaging surface will best adapt itself to the particular form and size of heel or other work to be operated on. The revo lution of the cables and disks holds them in the relation illustrated, and then under the pressure of the work they yield by virtue of the flexibility of the cables, of the bodily.

Yet theshifting is so resisted by the When heels of another form' or height are to be polished, it is a simple matter to remove the cables and disks by loosening the nuts 28 and replace them by others 'which may be better adapted for the purpose, the

head 16 being correspondingly adjusted if necessary. V
